Introduction

So the big question is: AOC AG322QCX or the Samsung CHG70? As always, I would say it depends. In image quality, the CHG70 is still a bit better. Especially, if you don't need a Motion Blur Reduction you can take a closer look into the AOC AG322QCX. In terms of the price, the AOC is more attractive. It also has a much better Freesync range (48-144Hz) compared to the Samsung CHG70 (80-144Hz, after the new firmware update the Samsung has 70-144Hz). Horizontal scan lines, as same as Text-Inversion issues also are visible on the AOC, even a bit less compared to the Samsung CHG70. Overall the AOC is a good choice, a good response time, solid blacks, decent VA Glow... The biggest issue for me is oversaturated and unnatural colors. Choosing the sRGB mode within the OSD could help but first, blacks become a very noticeable purple tint, and second, we cannot change brightness while the sRGB mode is chosen. So, let's take an in-depth look into the AOC.

IMPORTANT(!) Updatesand new information about the AOC AG322QCX can be found at the bottom of the article or in the table of contents (if available). Also available within the forum (click here).

Pros & Cons

Pro:

- Very good contrast ratio and clearly over the stated 2000:1- Freesync with a range between 48-144 Hz + AMD LFC(Low Framerate Compensation)- Excellent blacks- Good build quality- Nice foot stand and good ergonomics- Good OSD navigation- Good VA viewing angles- Good overdrive settings- Very low input lag- Included OSD navigation USB device- Very good uniformity

Neutral:

- Good but not "perfect" gamma settings- Added sharpness which cant be removed- Half matte panel coating- Loud Humming sounds on pixel inversion test pattern(also a bit of brighter image content)Update: Can be avoided when setting the volume to 0- Some VA black crush issues- A bit of clouding on the top and lower bezels

Contra:

- Vertical Scanlines + Text Inversion as same as on the Samsung CHG70 (a bit less visible)- Colors have a red tint and look sometimes to oversaturated, even against the Samsung CHG70- The VA typical "VA Glow"- sRGB mode is pretty useless (blacks getting purple and huge color banding issues in sRGB mode)
